l'o all Vwlw/n. it may concern.' l

lie it known, that l, Erna H. S'rxmfono, a citizen of the United States,and resident of rlencoe, county of Cook, and' State ot Illinois, haveinvented certain new and useful Improvements in Combined Seats andDesks, of which the following is a. specification, and which are-illustrated in the accompanying drawings, VJfoi-min,r a part theriof.

The invention relates to combined seats and desks especially adapted forschool purposes. The objects et' the invention are to provide a portableIstructure which is adj-nstable to accommodate pupils varying in size;to provide for the easy assenibling and disassembling of the parts, andfor securely holding them when assembled and adjusted; land to improvesuch devices in various details.

' @ne embodiment of the invention is hereinat'ter described, and isillustzwted in the accompanyingl d 'awings in which-- Figure 1 is afront elevation of the device;

Fig'. 2 is a side elevation thereof showing different positions ot' thedesk in dotted lines;

Fig'. 3 is a plan section on the line SM2-S of Fig. 2;

Fig. fl is a detail vertical central section on the line 4 4 of Fig. 3;

Fig. 5 is a sectional detail ot' the ad j ust- Y able desk support; and

Fig. (5 is a detail, partly in section, ot' the side of the seat showinga book receptacle. 4

The seat comprises a suitable frame having,` side members 10, *11, andcross members 12, 13; and aback which comprises the uprights 14, if, anda panel portion 16. rll`he bark .is secured to the side members of theYframe, by means ot' screw-bolts, such as those shown at i7, 1S, whichare readily removable. 'lhe sides l0 and lll tre continuousstructuresjthough pretera if are coved out at the bottom, as indicatm` at 197 20,providing Yfront and back i'eet.

'lhe bottom 21 of the seat is provided with depending 'front and backcross-members 22, 23, and with side plates 24, 25, preferably of metal,and spaced to loosely enter between lhe 'frame members Uh VIl. 'lheseplates are vertically slotted, as shown at eo, 27,

2H QSL lo receive tie-rods El() 8l oit' the frame and are provided withsuitable nuts. The bottom is, therefore, vertically adjustable, and isrigidly secured in any adjusted position by means ot' the tie-rods.

In order to provide for vertically7 adjusting the bottom whilennlintainine` its proper inclina-tion, there is shown a removableraising and lowering' apparatus comprising a pair of parallel bars1 52.l2-l, adapted' to it in apertured plates Si, Elm-secured, respec tively,to the er(iss-members 22, Q3, of the bottom and the erosssbars l2, 13,of the frame; a rod lo having at each end right and lett screw threads.as shown at 37, 38, upon which run nuts 3i), 4:0, l and 2, each ot whichis eonneeted, by means of a pair of 'links eil-3, il, l5 and i6, withthe bare 32, 33, thereby forming; two double toggles A crank arm L7 isfixed to the reir end et upwardly above the seat bottom and sup portsthe desk.

The desk comprises a bracket l-l. 'formed ot' a pair ol2 side plaies5l), 5L whieh are secured to instandingi flanges ol' a plate attached lothe upwardly projectinpr por,

tion of the wall extension 4S, this attach-- ment being; b v means ofapair of boils 53, 5l, whieh pass llhrougrhslots, as 55? in the flangesot' the plate 52 and are provided with suitable nuts., as .shown at 5G,i'iQ-Yl'hus permitling ;l the raising' and lowerinpv oli the side platesand providingl tor rigidlyv secar ing' iheni in their adjustedpositions. Il`he desk comprises further a table. 58 provided with a pairol depending plaies 5S), (3()n whieh are pivotedpas shown at (Si, to thecross nien'ibersl` as G2. olf the bracket i9 adjacent their rearwardends, and are secured to such cross members at their forward ends bymeans ot' winged nuts (33, (il, engagjing;- studs ixed in the endmembers olf the bracket and settingf 'through rurved slots.) as o5, inthev plates 5S), (Si). 'lhe table may, therefore` be tilted upwardly atits forward end lo give it such inclination as the user 2 reo inaypreiier, and may be locked .in its adjusted position by means ot thenuts G3, Gl,

The plates 59, 60, are flanged in iardly at their Upper edges, as shownat 6G, each of these flanges litting between a pair of plates 67, G8,secured to the under face of the table by means of screws 69, 70,adjacent their ends. The plates, 67, 68, being of greater length thanthe flanges 66, the table may be adjusted horizontally and, if desired,may be firmly secured in any adjusted position by tightening up thescrews e9, 7e. f

The table, therefore, has three adjustinents,-vertically by reason 'otthe sliding' engagement of the snpportingr bracket with the side of theseat; it may be tilted about the' pivots Gl; and it i'nay be movedbackwardlyv and forwardly between the guide plates 67, 63. The desk maybe readily removed from the seat by withdrawing the bolts 53, 54, andthe several inen'ibers of the table may be disconnected from each otherand from the bracket.

A book receptacle 71 is attached to one of the side walls oli' the seatframe, and coinprises an outwardly bowed body portion which may be ofmetal or of wood and having a, bottom 72. The edges of the body portonof the box slide vertically in ways 73 attached to the side Wall of theseat frame. The top of the box is covered by ineens of a lid 74C, hingedto the. seat traine, and when raised permitting the body portion of thebox to be drawn out 0 1c the slide- Ways.

The device as shown and described does not require to be attached to theiloor, and may therefore be readily inoved to clear the floor forcalistlienics or other school exercises. It may be adjusted in severalways t0 suit the size and convenience of the occupant. It is easilyassen'ibled and disassembled, thereby facilitating and cheapening'shipment and storage.

While I have shown and described a pre- 'ferred embodiment of theinvention, various changes may be made therein without departing fromits scope.

I claim as my invention-- il. ln a combined seat and desk.` incombination, a frame. comprising a pair ot side 'Walls and a back, oneof the side walls being' forwardly extended, a. bottom verticallyadjustable on. the frame., a desk carried by the forward extension ofthe lrame side and being; vertically adjustable.
